JOHN COMES, CF RUSHVILLE, OHIO, ASSIGNOR OF ONE-HALF TO CHARLES A. THOMAS, OF SAME PLACE.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 299,962, dated June 10, 1884..

Application filed March 18, 1884. (No model.)

, To all whom it may concern.-

Be it known that I, JOHN (Jones, a citizen of the United States of America, residing at Rushville, in the county of Fairfield, in the State of 5 Ohio, haveinvented a new and useful W'rench,

of which the following is a specification.

My invention relates to improvements in that class of wrenches generally known as ratchetwheel wrenches, and the object thereof is to provide such an implement that will be simple, durable, and inexpensive in its construction, easy of manipulation in operation, and readily adjusted to suit the varying sizes of nuts, or of other articles to which its use is applicable,

I while at the same time the several operative parts of the wrench being independently fashioned, can be readily replaced in case of fracture. These objects I attain by the construe tion as illustrated in the accompanying draw- .20 ings, in which Figure l is a perspective view of my improved wrench. Fig. 2 is a view of a horizontal section of the same. Fig. 3 is a detail view of the handle. Fig. 4 is a detail view of the pawl, and Fig. 5 is a sectional view, taken through the line w w of Fig. 1.

The letter A represents the handle, construct ed of any suitable material,with one end thereof cut out half-round, as shown by Fig. 4.

This cut'out portion of the handle forms a seat for a circular block, B, which is held in place bya spring-band,O, passed around said block between the flanges b, and seeuredin any suitable manner to the handle. The periphery of 3 5 this block between its flanges b is formed with a series of ratchet-teeth, which engage apawl, 13, made preferable lshape, and inserted in a correspondingly'shaped slot, (1, in the handle A under the band C,which is made of spring 40 material,to more readilyinsure the engagement of said pawl and ratchet-teeth. The circular flanged and ratcheted block B is cut out rectangularly in its center, the longer faces of the rectangle being provided with L-shaped grooves,

5 while near one end thereof is located a partition, 0, having a central perforation.

Working in the central perforation in the partition 0, and a similar perforation in the block B, registering therewith, is a screw, f, to

one end of which, below said partition, is socured a follower, E, formedwith lugs g,adapted to slide in the grooves upon the faces of the rectangular opening, said grooves being made L-shaped to admit of the insertion of the follower.

or other article to be operated upon, this follower and the faces of the rectangular opening adjacent thereto forming the bite of said wrench.

justment of the wrench to the size of the nut Adapted to be placed in the follower-grooves 5 of the rectangular openings in the circular block are short blocks 71, which limit the ex tent of the followers adjustment and prevent the same from becoming disconnected when screwed down, though said blocks maybe omit- 7 ted, if desired.

In the operation of my invention, the follower G is properly adjusted in the rectangular opening oftheblock B to suitthesizeofthe nut upon which the'wrench is desired to be used,by 7 means of the screw f and screw-threaded sleeve or thumb-nutg. The wrench being now placed in position upon the nut, the handle A isoperated in a direction opposite to the pitch of the ratchet-teeth upon the periphery of the cirs cular block, thereby loosening or tightening said nut, as occasion may require. Should there be any obstacle preventing the entire revolution of the wrench, the handle A, after reaching its limit, is brought back and a new 8 hold obtained for the pawl, the circular block remaining stationary, and this operation repeated as often as necessary.

Having now described my invention, what I claim is- 1. A ratchet-wheel wrench consisting of a handle having one of its ends cut out half round, a pawl set in the side of the handle, a circular block flanged and ratcheted upon its periphery, and provided with a central opening, and a springband arr. nged about the circular block and over the pawl and fixed to the handle, substantially as described, and for the purpose set forth.

2. A ratchet-wheel wrench consisting of a I handle having one of its ends cut out halfround, and one of its sides at this endprovided with a groove adapted to receive a pawl and hold it from lengthwise and lateral move- 5 Inent, in combination with a circular block flanged and ratcheted upon its periphery, and provided with a central rectangular partitioned opening having grooves upon its longer faces, a follower adapted to work in said open- IO ing and grooves, a screw, and screw-threaded sleeve or thumb-nut for operating said follower, and a spring-band whereby the circular block, handle, and pawl are secured and rendered operative, substantially as described.

In testimony whereof I have hereunto set my I 5 hand in thepresence of two attesting witnesses.

JOHN COMES. Attest:
